The body of a 14-year-old boy has been found in the River Thames.
Emergency services were called to an area of the river near Donnington Bridge, Oxford, at around 5.30pm on Wednesday.
Thames Valley Police said the boy’s death was being treated as ‘unexplained but not suspicious’ and that his family had been informed.
This marks the 11th water-related death since the UK was plunged into a record-breaking heatwave late last week, nine of whom were young people.

It comes as the UK continues to endure a record-breaking heatwave.
Tuesday was the hottest May day on record when Kew Gardens in London reached 35.1°C, smashing the previous record – set the day before – by a staggering two degrees.
A spokesperson for the National Water Safety Forum (NWSF) said it is too early to say whether the number of water-related deaths during this heatwave is ‘unusual’.
But the NWSF said hot weather often correlates with an increase in accidental drownings.
The spate of deaths has prompted the Royal Life Saving Society (RLSS) to issue a water safety warning, urging swimmers to be aware that water temperatures remain cold even in extreme heat.
They said cold water shock can make swimming and exiting the water harder.
